Angle ADB is a right angle --- Given

Angle ADB is 90 degrees --- Definition of a Right Angle

Angle CDB is 90 degrees --- Definition of Supplementary Angles

Angle ADB = Angle CDB --- Definition of Congruent Angles

Proofs can be tricky! What helps me is thinking through them step by step and how I would prove I did something. While I'm not entirely sure what options you have for this proof, I've given my best guess.

Hope this helps!! :)

Determine whether the graph below is a function.<br> Answer True if it is and False if it is not.
kramer

Answer:

<em>Answer: False</em>

Step-by-step explanation:

<em>Relations vs Functions</em>

For a given relation between two variables x and y to be a function, it must meet the following condition: every value of x must be related to one and only one value of y.

When the graph of a relation is given, we can easily tell the difference by using the vertical line test as follows:

Imagine a vertical line moving through the x-axis. If any line touches the graph of the relation at more than one point, then the relation is not a function.

If we place vertical lines through the x-axis, they would touch the function twice at some values of x.

Thus, the graph is not a function

Answer: False

Options for first blank: V=PR V=(PR)^(1/2) V=P^2R Options for second blank 16 5 4
oksano4ka [1.4K]

Answer:

The formula to find the voltage is:

v=\sqrt{P*R}

And the voltage is 4 volts

Step-by-step explanation:

To get the equation of voltage you need to isolate v in one side of the equation. In order to do that, you need to remove the divisor/denominator and its square. How will you do that?

First, multiply both sides with R:

P*R=\frac{v^{2} }{R} *R

That would result into removing the divisor R from the right side of the equation:

P*R=v^{2}

Next, square-root both sides:

\sqrt{P*R} =\sqrt{v^{2} }

That would result in removing the square of v from the right side of the equation:

\sqrt{P*R} =v

Thus we get the equation, v=\sqrt{P*R}.

To find out the voltage, simply replace R with 32 and P with 0.5

v=\sqrt{0.5*32}

r=\sqrt{16}

r=4

Thus, the voltage is 4 volts.
